1.Introduction:
Needle coke is a high-quality petroleum coke with low impurities and high thermal conductivity. It is mainly used in the production of graphite electrodes, a crucial material for electric arc furnaces used in the steel industry. Needle coke is an expensive and limited resource, and its production requires a complex process.
2.Specification:
Pet coke: (Size:0-20mm)
Calcined:(Size: 0-1mm, 1-2mm, 2-4mm, 4-6mm, 6-20mm, or at customer's demand)
3.Application:
Medium sulfur, common cooked coke, widely used in aluminum smelting.
High sulfur, common coke, is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting fuel.

- Q: Please explain carbon black, coke, graphite, activated carbon What is the difference in molecular structure
- Graphite is a crystalline carbon. Hexagonal system, for the iron color to dark gray. A density of 2.25 g / cm3, a hardness of 1.5, a melting point of 3652C, and a boiling point of 4827C. Soft, greasy feeling, can be conductive. Chemical nature is not active, corrosion resistance, and acid, alkali and other difficult to react. Heat in the air or oxygen to heat, can burn and generate carbon dioxide. The strong oxidizer oxidizes it to an organic acid. Used as anti-friction agent and lubricating material, making crucible, electrode, dry battery, pencil lead. High purity graphite can be used as a neutron descaling agent in nuclear reactors. Often referred to as charcoal or black lead, because it was previously mistaken for lead.
- Q: Is it better to use formaldehyde in addition to formaldehyde?
- As far as I know the activated carbon in addition to formaldehyde will be secondary pollution, adsorption saturation after a rise in temperature will be re-released, you can use Egyptian carbon crystal can be adsorbed or can be decomposed material or processed by the adsorption more Strong activated carbon type in addition to formaldehyde. I hope I can help you.
- Q: Is activated carbon a hazardous chemical? Are waste activated carbon hazardous to waste?
- Hazardous waste refers to emissions of one or more hazardous characteristics, such as corrosive, toxic, flammable, reactive or infectious, and that is not hazardous to hazardous substances, which may adversely affect the environment or human health, Need to be managed in accordance with hazardous wastes.
- Q: Why is activated carbon adsorbable?
- Activated carbon is a porous carbonaceous material, its developed structure of the gap so that it has a large surface area, there are more small particles in the pores - capillary, this capillary has a strong adsorption capacity, due to the surface area of carbon particles It can be in full contact with the gas (impurities), when the air in the toxic gases and activated carbon contact, activated carbon hole around the strong adsorption force field will immediately poison gas molecules into the hole, so the activated carbon has a strong adsorption capacity.
- Q: What are the advantages of graphene powder compared to activated carbon?
- Gypsum has a large specific surface area and strong adsorption properties, which can be combined with conventional photocatalyst products to improve its performance. For example, the sensitivity to UV conditions is reduced and the common light can stimulate the reaction.
- Q: Is graphite a high molecular material?
- Polymeric materials: Materials based on polymer compounds. Polymeric materials are made of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings,
- Q: What is the difference between volcanic ash and activated carbon adsorption?
- Activated carbon adsorption capacity
- Q: What is the difference between graphite and activated carbon?
- Graphite is a single element of carbon, no holes;
- Q: What is the difference between the adsorption of graphene and activated carbon
- The size of the adsorption capacity often like to use the specific surface area to measure ... and the specific surface area of graphene is much larger than the activated carbon ... but graphene is not like activated carbon ... there are a lot of microporous structure ...
- Q: Why just renovated the house put plants, activated carbon, bamboo charcoal, the taste is still great
- If the newly renovated house put plants, activated carbon, bamboo charcoal, the taste is still very large, then the reason is airtight ventilation.
